Brand New in Box (New Old Stock) • Lists at $225 - Save $$$ FAST Shipping - Ships same/next day via FedEx for US Bidders! Whenever you need to connect consumer gear to professional equipment, Matchbox is the way to go! Matchbox eliminates the hum, buzz, and distortion caused by mismatched levels and impedances. Matchbox is ideal for devices that play and record, such as DAT recorders and computer sound cards. Don't trust your audio to inexpensive units that are powered with "wall-warts"! Superb audio performance is why we've sold over 50,000 units worldwide. Product Description The rack-mountable Matchbox is the industry's most popular analog level and impedance converter. Matchbox offers a true 100 dB S/N ratio, with 22 dB of headroom to yield 122 dB of dynamic range. It is the very best way to interface "consumer" or semi-pro equipment with professional audio gear. The Matchbox is a bi-directional unit, employing four independent amplifiers to convert stereo inputs and outputs from unbalanced -10 dBv levels to +4 dBm balanced 600 ohm lines. All four outputs can be adjusted to accommodate a wide range of operating levels. The unit’s direct-coupled circuitry and exceptional dynamic range provide absolute sonic transparency, making Matchbox ideal for use with digital editors, DAT recorders, and other digital audio sources. The Matchbox HD has an internal AC 115V dual voltage power supply which can be re-strapped internally for 230V working.
